Chinese D-Series Paper Size Lookup
Was this tool helpful to use?
Your feedback helps us make it better
Look up exact millimeter dimensions for D0 to D6 series paper based on the GB/T 19999-2003 national standard, suitable for book, magazine, and office paper design.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This reference table shows Chinese paper dimension data in millimeters. It has D0–D6 rows labeled Standard D and 1K–128K rows labeled Four-Six; the latter provide separate A and B dimensions. Read the type column before relying on a familiar code such as D4 or 16K. Dimensions are shown as short edge × long edge, so a landscape layout simply swaps the two numbers.
The D labels here refer to a Chinese paper-size context. They should not be confused with similarly named US drawing sizes or assumed to be universal. The official standard record identifies GB/T 148-1997 as current on 2026-09-28 and GB/T 148-2026 as its replacement effective 2026-12-01. IANA’s printing-media registry lists D0–D6 dimensions. These sources do not validate every Four-Six A/B entry in this table.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Use Standard D for a D code such as D4. Use Four-Six for a K code such as 16K, where the page shows separate A and B values.
Search by a code or a distinctive dimension to narrow the rows. Check the type column whenever the search term could match more than one naming system.
Values are short edge × long edge. For a horizontal page, reverse the order rather than looking for a different paper code.
When setting up a file or requesting paper, record the full code and millimeter dimensions together, such as D4, 188 × 260 mm. Ask the printer or supplier to confirm the intended size set and finished dimensions.
Use cases
See how the tool fits into real work and everyday tasks.
A designer can look up a D code and enter its short-edge and long-edge values in the page setup, then orient the layout as needed.
Include the code, both millimeter dimensions, and whether the request is for stock or finished trim size. Ask the supplier to confirm when the brief only says “16K” or another abbreviated name.
Share the sizing-set label as well as the numbers. When the Four-Six row has A and B variants, have the production contact confirm which entry applies before locking the artwork.
Q&A
Find concise answers to common questions and confusing cases.
The table lists D4 as 188 × 260 mm, short edge by long edge. Its approximately landscape orientation is 260 × 188 mm.
No. This page’s D0–D6 labels belong to a Chinese paper-size context. US drawing size letters describe a different sizing system; use the dimensions and standard named in your specification.
Four-Six rows display separate A and B values. They are entries in the table, not a tolerance range. Confirm the required variant with the originating specification or print provider.
Notes
Review scope, result limitations, and important precautions before use.
A lookup is a reference aid. It does not verify printer feed limits, bleed, binding allowance, stock availability, or the requirements of a particular contract.
